Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

Code Review

When to use this skill

  • Reviewing pull requests
  • Checking code quality
  • Providing feedback on implementations
  • Identifying potential bugs
  • Suggesting improvements
  • Security audits
  • Performance analysis

Instructions

Step 1: Understand the context

Read the PR description:

  • What is the goal of this change?
  • Which issues does it address?
  • Are there any special considerations?

Check the scope:

  • How many files changed?
  • What type of changes? (feature, bugfix, refactor)
  • Are tests included?

Step 2: High-level review

Architecture and design:

  • Does the approach make sense?
  • Is it consistent with existing patterns?
  • Are there simpler alternatives?
  • Is the code in the right place?

Code organization:

  • Clear separation of concerns?
  • Appropriate abstraction levels?
  • Logical file/folder structure?

Step 3: Detailed code review

Naming:

  • Variables: descriptive, meaningful names
  • Functions: verb-based, clear purpose
  • Classes: noun-based, single responsibility
  • Constants: UPPER_CASE for true constants
  • Avoid abbreviations unless widely known

Functions:

  • Single responsibility
  • Reasonable length (< 50 lines ideally)
  • Clear inputs and outputs
  • Minimal side effects
  • Proper error handling

Classes and objects:

  • Single responsibility principle
  • Open/closed principle
  • Liskov substitution principle
  • Interface segregation
  • Dependency inversion

Error handling:

  • All errors caught and handled
  • Meaningful error messages
  • Proper logging
  • No silent failures
  • User-friendly errors for UI

Code quality:

  • No code duplication (DRY)
  • No dead code
  • No commented-out code
  • No magic numbers
  • Consistent formatting

Step 4: Security review

Input validation:

  • All user inputs validated
  • Type checking
  • Range checking
  • Format validation

Authentication & Authorization:

  • Proper authentication checks
  • Authorization for sensitive operations
  • Session management
  • Password handling (hashing, salting)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
